后台返回Object/Map类型，前端接收到的类型也会不同

1、后台返回类型是Object，前端android接收到的也是Object

            }

            /**返回Object类型**/
            LayerInfoConfig layerInfoConfig = new LayerInfoConfig();
            layerInfoConfig.setLayerList(layerList);

            return new ResponseObj<>(layerInfoConfig, null);
        } catch (Exception e) {
            e.printStackTrace();
            return new ResponseObj<>(null, new Error(-1, "服务器请求异常"));
        }

    }

前端

     *
     * @return
     */
    @GET("layer/selectLayerList")
    Observable<ResponseObj<LayerInfoConfig>> getLayerInfo(@Query("userId") String userId);

                });
    }

2、后台返回类型是Map，前端android接收到的也是LinkedTreeMap
